Imagine the 2018 World Cup without any Premier League players. It’s inconceivable, isn’t it?

Yet the Winter Olympics’ men’s ice hockey tournament is missing many of its biggest stars because of a row with North America’s National Hockey League (NHL) – the sport’s most popular competition in the world.

How did this happen, and will it affect the Pyeongchang Games? BBC ice hockey commentator Seth Bennett explains.

What has happened?

The National Hockey League, which is the top men’s league in the world, has refused to allow its players to compete in the Winter Olympic Games. That’s somewhere between 150-180 players stopped from competing on the world’s biggest stage.

The NHL board, which runs the league, is made up of the owners of the 30 individual teams.

The time difference between Korea and North America means many of the ice hockey games are being played in the middle of the night for US audiences and the NHL therefore felt it was not right to put their league on hold for three weeks and allow its players to go to Pyeongchang.

There was even talk of strikes as a number of high-profile stars like Sweden’s Henrik Lundqvist and Russia’s Alexander Ovechkin expressed a desire to represent their nation and the event.

How did we get to this point?

Captain of the Washington Capitals, Alexander Ovechkin, will not be allowed to represent OAR (Olympic Athletes from Russia) at the Games

Since the Olympics in Vancouver in 2010 the NHL and the International Olympics Committee (IOC) have had an uncomfortable relationship.

The NHL questions the business reason for sending its prize assets to the Games, whilst not receiving the level of compensation or the upturn in international interest in the league that it hoped.

In short, it is down to money.

Injuries in Sochi four years ago were cited as one reason, with the NHL also seeking compensation for having to shut the league down.

But the IOC does not pay any professional league or organisation to ensure participation – and so the two parties refused to budge, meaning a deal for the best players in the world to be in Pyeongchang could not be reached.

It will be interesting to see if the NHL is willing to take a similar stance when the Games move on to Beijing in four years.

China is a market which has been coveted by a number of sports because of people reach and commercial opportunities. The NHL has already made its own overtures, holding pre-season games there in 2017 with commissioner Gary Bettman in attendance.

What has been the reaction?

New York Rangers netminder Henrik Lundqvist, who won gold with Sweden in 2006, tweeted his disappointment when he heard the decision in April 2017

The players’ union said it was “extraordinarily disappointed” with the NHL’s “short-sighted” decision, adding: “players are patriotic and they do not take this lightly”.

The decision has also been met with frustration and disappointment from fans and from the players, with Lundqvist tweeting that they were missing out on the “most special adventure in sports”.

Since 1998, when the NHL and the IOC first agreed for its players to feature in Nagano, the Olympics has been seen as the pinnacle of the sport for the players.

For many of the non-North America players it was a chance to showcase their talent in their own country, something which the majority haven’t done since their formative years on the ice.

The various national governing bodies have been forced to find the next echelon of players, which for some of the general managers has meant spending the last 12 months travelling around the world to watch all the possible options play.

Who are the star names missing out?

Russian winger Ovechkin plays in Washington and is one of the most explosive players in world hockey.

Lundqvist backstopped Sweden to a gold medal in Turin in 2006 and then to silver in 2014 in Sochi. Lundqvist is now 35 and is unlikely to get another shot at Olympic glory. However his twin brother, Joel, will play for Sweden in Pyeongchang.

Other absentees include the NHL’s Most Valued Player from one season ago, Connor McDavid of the Edmonton Oilers. He is considered the fastest player in the game. The USA’s Jack Eichel is another top player under the age of 21 and Russian forward Nikita Kucherov of the Tampa Bay Lightning is enjoying a breakout season and currently leading the NHL scoring charts.

So how will it affect the action?

The standard will definitely take a hit. The drama will not.

All you have to do is look back to the last time NHL players were not participating in the Olympics: Lillehammer 1994.

There’s no doubt, with the absence of the world’s best players, the quality will not be as strong as Olympics past.

However, with the tournament featuring no clear-cut favourite, there are at least five nations (Olympic Athletes from Russia, Sweden, Finland, Canada and Czech Republic) who could vie for gold. This will make the drama high and the games intense.

Who are the stars left and who are the favourites?

Ilya Kovalchuk (OAR) is expected to shine in the absence of NHL stars

The Russian team, OAR, have to be seen as the number one seed.

Featuring players from the Kontinental Hockey League – regarded as the second best league in the world behind the NHL – OAR will have plenty of firepower from the likes of superstar forwards Ilya Kovalchuk, Pavel Datsyuk and Sergei Mozyakin.

Canada boasts a strong line-up of former NHL players who now ply their trade in the European leagues.

Sweden, who always play a very high-tempo structured game, will include players from the SHL – Sweden’s highest domestic league.

Many eyes will be on Swedish 18-year-old Rasmus Dahlin, regarded as the number one prospect in the world.

What about the women’s event?

The women’s tournament is unaffected and should come down to a USA v Canada final – as has been the case for the previous two Olympics.

However, the gap between the superpowers of USA and Canada is starting to close.

Sweden has a very disciplined team with plenty of depth through their line-up. Veteran forward Pernilla Winberg will be looking for a medal in her fourth Olympics.

Finland, with stalwart goaltender Noora Raty, and Switzerland will also be competitive.

Hosts Korea will not make too much of an impact on the ice, but the story of the unified team and political recourse is sure to be a major story throughout the Games.
